Abstract (en)
Embodiments of this application provide a communication method and a network device. The method includes: determining, by a network device, that a resource corresponding to at least one DMRS port of a plurality of DMRS ports of the network device is not used to transmit a DMRS in a first time segment; determining, by the network device, a first resource used to carry, in the first time segment, first data information to be sent to a terminal device, where the first resource includes the resource that is corresponding to the at least one DMRS port and that is not used to transmit the DMRS; sending, by the network device, indication information of the first resource to the terminal device; determining, by the terminal device based on the received indication information of the first resource, the first resource used to carry the first data information in the first time segment; and receiving, by the terminal device from the network device, the first data information carried on the first resource, or sending, by the terminal device, the first data information to the network device by using the first resource to carry the first data information. In this way, the network device and the terminal device transmit data information by using the resource corresponding to the idle DMRS port. This improves spectrum efficiency.
